Printable Ring Size Guide

Blue Nile realizes that you may not know the ring size for a given finger, and we want to help. We provide a printable ring sizer that can help you determine your ring size. Prior to printing, ensure that page scaling is set to "none" on your print dialog box.

Find Your Perfect Ring

Free Resizing

Blue Nile provides complimentary resizing for Build Your Own Rings®, and Diamond Bands when within the manufacturer's recommended sizing range, during the first year. Simply contact a Diamond & Jewelry Consultant at 1800-242-2728 to arrange for your free resize. You will be responsible for the cost of returning the product, according to our return policy.

Diamond and gemstone eternity rings with a specific number of gemstones per finger size; milgrain or ornate bands, some silver rings, or rings with alternative metals such as Tungsten cannot be resized. We are happy to exchange your ring for another size within 30 days of purchase. It is important to note that should you opt for an exchange, your new ring may contain fewer or more gemstones, diamonds, or a reduction or increase in precious metal weight which may cause an increase or decrease in the price.

International Size Conversion

If ordering from outside of the US or Canada, determine your ring size according to your country’s standard. Then use the International Ring Size Chart to convert to the corresponding US ring size to place your order.
